Parametric Variations - Quick Start Form

Use the Parametric Variations - Quick Start form to specify a parametric variation using template alignments.

Select a Quick Start Option area. Several linear, circular, parabolic, and combination alignments have been included as default templates. Choose an alignment option for the variation by clicking on it. If the exact alignment is not shown, choosing one that is close can help speed the specification process because the template alignment can be modified after the OK button on this form has been clicked.
Set Length for Parametric Variation area. In this area of the form, choose to use previously defined segments or to specify an individual segment span.
- From Bridge Object and Span option. When this option is selected, use the drop-down list to specify the Bridge Object and the Span ID to be used to define the span segment or entire bridge length when applying the selected template. Thus, after a segment has been defined in a Bridge Object, that definition can be reused in any parametric variation definitions within the same model file. The selections available in the Span ID drop-down list depend on the Bridge Object selected in the Bridge Object drop-down list. If this option is not available, no bridge spans have been defined for the model.
- User Specified Length option. When this option is selected, also provide a value in the Span Length edit box to specify the length of the parametric variation in the current units measured from the left end of the bridge.
Units drop-down list. Use the displayed units or select revised units from the list for use on this form.
OK button When this button is clicked, the selected alignment will automatically transfer to the spreadsheet area of the Variation Definition form, where it can be reviewed, and if necessary, further refined.
